Sims are run every day, if that's what you mean. If you look at the top right of the screen, you'll see we're in FA stage 4 of 6.
About financials and how much you have left, go to your team page, there you will find your cap situation.
The one thing I'd suggest JD to add to that part is how much of the cap money you have left approx. is tied to draft picks. Right now I figure it out by making a contract offer and then upping the salary bar until the game tells me that could put me over the cap. Not ideal.
